  <title>Bug 1130686 - Test service worker client.focus </title>
  <script type="text/javascript" src="/tests/SimpleTest/SimpleTest.js"></script>
  <link rel="stylesheet" type="text/css" href="/tests/SimpleTest/test.css" />
<!--
  This test checks that client.focus is available.
  Actual focusing is tested by test_notificationclick_focus.html since only notification events have permission to change focus.
